I'm sure you would like to join the happy folk frolicking above. But perhaps you enjoy more cerebral pleasures. So I have a suggestion.
Our friends at Delong's Wine info have started the Wine Century Club for those who have tried wines from over 100 varieties. They have even devised a checklist to help you keep count.
Membership is free, but only open to those who can honestly say that they have tried 100 varietals. So use the link below to download your checklist. While you are there, why not check out the Wine Variety Table and Index that they have for sale. It's a great resource for learning about wine.
